1. Farm-Raised Salmon

While farm-raised salmon is big business here in the US, it is illegal in Australia and New Zealand. Because the fish are basically mass produced, they are fed synthetic astaxanthin made from petrochemicals.

While it may be safe for fish to eat, the stuff has not been approved for human consumption.

2. Processed Foods Containing Artificial Food Colors and Dyes

Norway, Austria, and other countries in the European Union have banned the sale of foods containing harmful dyes like red 40, yellow 5, yellow 6 and/or blue 2 which happen to be the most commonly used food dyes in the US. They have been linked to toxicity and hazardous health effects.

Kraft was put on blast for using yellow 5 in their famous macaroni and cheese recipe here in the U.S. It was never present in boxes sold in Europe.

3. Olestra/Olean

Created by Procter & Gamble as a substitute for cooking oil, Olestra prevents the body from absorbing vitamins. It is banned in the UK and in Canada for its harmful side effects, including stomach cramps and leaky bowels.

4. Preservatives BHA and BHT

BHA (butylated hydroxyanisole) and BHT (butylated hydroxytoluene) are preservatives that are often found in long-shelf life products like breakfast cereals and chewing gums.

The UK has banned the use of BHA in baby food and both BHA and BHT are banned in Japan and parts of the European Union.

5. BVO

Artificial flavor and color isn't the only thing that shows up in soda in the US. Mountain Dew and other citrus-flavored soft drinks contain BVO, or brominated vegetable oil. The chemical was actually created to be a flame retardant and consumed in large quantities, can cause damage to your nervous system.

It is banned as a food additive in Europe and Japan.

6. Arsenic-Laced Chicken

Arsenic-based drugs can be used in some animal feed in the US because they can help animals grow quicker. They also can create pinker flesh in animals. It appears in commercial grade chicken feed since the US Food and Drug Administration (FDA) has stated these products are safe.

In the European Union, arsenic-based feeds are banned as are the sale of chickens who have been fed from them.
